Which term describes knowledge of grammar, vocabulary, and pronunciation?

• A. Discourse Competence
• B. Linguistic Competence
• C. Register
• D. Style

Answer: (B)

Linguistic competence is the internal knowledge of a language’s structure—grammar, vocabulary, and pronunciation. It’s about knowing how the language is formed and sounds, not about using it in real situations.

This term best fits because it focuses on the foundational language knowledge that underpins accurate sentence construction, word choice, and phonology. Discourse competence, by contrast, concerns how to link ideas into coherent spoken or written texts. Register refers to language choices shaped by context, purpose, and audience. Style covers the manner or character of expression, including formality and tone.
